DNAPrint Pharmaceuticals / Harvard Medical School Study Shows Why PT-401 Is 'Significantly' More Effective Than Epoetin

DNAPrint Pharmaceuticals / Harvard Medical School Study Shows Why PT-401 Is 'Significantly' More Effective Than Epoetin

SARASOTA, FL -- (MARKET WIRE) -- 06/26/07 -- DNAPrint Genomics, Inc. (OTCBB: DNAG) today announced the results of a new study conducted to understand the binding of PT-401 and Epoetin to the EPO receptor in an attempt to explain why the Company's proprietary PT-401 protein is 'significantly' more effective than another prevalent drug, epoetin, in raising red blood cell counts.

The study revealed that less PT-401 is bound to the receptor and less is inactivated (inactivation is mostly done by a receptor-mediated clearance mechanism) resulting in a prolonged half-life. This binding feature of PT-401 explains the superior in vivo activity, implying important beneficial effects in patients. The study was presented by Dr. Sytkowski as part of the Annual Meeting of the European Renal Association in Barcelona, Spain, on June 23, 2007.

The experiments were conducted by the Company and Dr. Arthur Sytkowski, the Director of the Laboratory for Cell and Molecular Biology at Beth Israel Deaconess Medical Center (BIDMC) in Boston, an affiliate of the Harvard Medical School.

"Dr. Sytkowski is one of the foremost scientists in the field of therapeutic protein research, particularly Erythropoietin," stated DNAPrint Chairman and Chief Medical Officer Hector J. Gomez, M.D., Ph.D. "This study brings us one step closer to the day that PT-401, which in our studies appears to be superior to epoetin, may be available to benefit dialysis patients who suffer from anemia. DNAPrint® Pharmaceuticals looks forward to continuing our collaboration with Dr. Sytkowski on this important project."

PT-401 is a "Super EPO," a more powerful erythropoiesis stimulating agent than Erythropoietin, a well-known drug used for the treatment of anemia. Previously, DNAPrint Pharmaceuticals, the Company's wholly owned subsidiary announced three successful milestones related to PT-401: the use of CHO cell lines, the use of SDS-PAGE, a well-established separation technique for the testing of cell lines, and a specially developed isoelectric focusing (IEF) method. The initial research has been conducted in conjunction with Dr. Sytkowski.
